Question

part a: standardization of a dilute naoh solution.

1. chemical equation for the titration reaction for the standardization of the naoh solution:

Explanation:

Step1: Identify reactants

Sodium hydroxide ($NaOH$) is a base. A common acid used for its standardization is potassium hydrogen phthalate ($KHP$, $KHC_8H_4O_4$).

Step2: Write reaction equation

The reaction is an acid - base neutralization reaction. The hydrogen ion from $KHP$ reacts with the hydroxide ion from $NaOH$.
$KHC_8H_4O_4+NaOH = KNaC_8H_4O_4 + H_2O$

Answer:

$KHC_8H_4O_4+NaOH = KNaC_8H_4O_4 + H_2O$
